**Abstract**
 The results are reported of a computational investigation of the effect of fibre aspect ratio on the stiffness of composite rods reinforced with rigid spheroidal inclusions. Steady-state three-dimensional deformations of composite rods containing up to 50 individual, randomly placed aligned spheroids are considered. Solution of the equations of elasticity for the entire 3D domain yields an effective tensile modulus for the composite rod. Statistical averages of the computed effective moduli are compared to the predictions of the Mori-Tanaka model for the stiffness of the short fibre composites. In addition, the effect is investigated on stiffness of random perturbations in fibre length around a mean value. 15 refs.
